Description

TECHNICAL AREA

The utility model relates to the technology of fitness equipment, in particular a multifunctional fitness device.

BACKGROUND

Common fitness equipment includes dumbbells, kettlebells and barbells, which can effectively strengthen human arm strength and chest muscles through long-term exercise and are very popular among fitness enthusiasts. In order to meet the fitness needs of dumbbells, kettlebells or barbells and to create a multifunctional fitness equipment, various fitness equipment-specific applications have been designed in the prior art, which are essentially based on a dumbbell. This means that a functional combination is based on a dumbbell, so that the dumbbell dominates in terms of the fitness experience and the kettlebell and barbell play an additional role. This also means that the fitness experience is dominated by a dumbbell and thus remains incomplete with a kettlebell or barbell.

In the current state of the art, a desired counterweight is often made available using a filling liquid, i.e. instead of a dumbbell, to ensure the complete robustness of a fitness device. In order to meet the multifunctional fitness needs with the desired counterweight (attachment with optional dumbbell, kettlebell or barbell), certain screw parts should be attached to connect to the external bar handle when the filling liquid has not yet solidified. When the screw parts are mounted on the counterweight, the filling liquid in the solidification process should be vented so that the filling liquid cannot completely overflow when the screw parts are attached, which leads to inconvenient assembly. There is also a safety risk, as the exhaust air from the subsequently solidified filling liquid cannot be drained off.

Description of the utility model

Based on the conventional deficiencies, the present utility model is based on the task of providing a multifunctional fitness device, suitable for solving the conventional problems regarding differentiated fitness experience when using kettlebells and barbells, inconvenient assembly when attaching the screw parts and unextractable exhaust air.

DETAILED DESCRIPTION OF EXAMPLES OF IMPLEMENTATION

In the following, the present utility model is described in detail using the embodiments in conjunction with the drawings. Embodiment I

As from 1 As can be seen, the multi-purpose fitness device according to the invention comprises a counterweight 1, one end of which is formed with a connecting threaded hole 3 to which a removable rod handle is connected, and on one side surface of which or on an end facing away from the connecting threaded hole 3 a handle 2 is attached.

In the present embodiment, no rod handle is attached to the connection threaded hole 3, while the handle 2 is connected to a side surface of the counterweight 1.

In the current version, the fitness device functions as a kettlebell, with which you can grab the handle 2 and then carry out training actions such as pushing, pulling up, lifting and throwing. In comparison to the conventional fitness device based on the dumbbell, the functionality of the present kettlebell remains optimally comprehensive and can therefore create a better fitness experience, since you are not influenced by the arrangement of the dumbbell when exercising.

Embodiment II

As from 2 and 7 until 12 As can be seen, the fitness device according to the invention comprises a counterweight 1, one end of which is formed with a connecting threaded hole 3 to which a removable bar handle is connected, and on one side surface of which or on an end facing away from the connecting threaded hole 3 a handle 2 is attached.

In the present embodiment, the connecting threaded hole 3 is designed as a threaded hole, wherein the two ends of the rod handle are formed with a respective external thread connection point matching the thread of the connecting threaded hole 3.

The counterweight 1 is provided with an outer shell 101 which can be filled with a certain liquid (not illustrated), one end of which is formed with an opening where an inner sleeve 103 is installed to which the already solidified filling liquid can connect. That is, the inner sleeve 103 mainly serves to bind the filling liquid. In order to create a beautiful decoration, a first outer sleeve 104 is attached to the outside of the inner sleeve 103, the connection threaded hole 3 being formed as a threaded hole in the first outer sleeve 104.

A gear ring 102 is attached to the outer wall of the inner sleeve 103, the inner wall of which is formed with a uniform internal toothing 1021, and the outer end face of which is formed with a uniform external toothing 1022, wherein the external toothing 1022 contacts the flange end face in the outer end face of the inner sleeve 103. In this case, the exhaust air from the filling liquid and filling liquid solidification, after the inner sleeve 103 has been assembled with the outer shell 101, can then be discharged through the gaps of the internal toothing 1021, gaps of the external toothing 1022 and a groove 1031 formed along the flange circumferential direction of the inner sleeve 103. The arrangement of the gear ring 102 mainly leads to the continuous connection of the inner chamber of the outer shell 101 with the external environment. Without this gear ring 102, the inner sleeve 103 cannot be inserted in the correct position and, in addition, the exhaust air cannot be discharged to the outside during the solidification of the filling liquid, which represents a safety risk.

In the present embodiment, the rod handle is designed as a short handle rod 406 with a rod body 401, at each of whose ends a connection rotary knob 406 is attached, which is screwed to the first outer sleeve 104.

The two ends of the rod body 401 are each formed with a polygonal stop head 403 which can engage in the inner chamber of the first outer sleeve 104 and then interact with the polygonal stop hole 1041 in the first outer sleeve 104 to prevent possible rotation of the first outer sleeve 104 relative to the rod body 5(401). In this embodiment, the stop head 403 and the stop hole 1041 are all positively polyhedral in cross section, but can also be positively square, positively triangular or positively octagonal.

The wedge 405 is attached to a height point of the connection knob 406. In the present embodiment, two wedges 405 are provided, which are arranged symmetrically along the circumferential direction of the connection knob 406. In the circumferential direction of the connection knob 406, a radial through hole 4061 is also formed, which is continuously connected to the centering hole and in which the wedge 405 can engage. A screw hole 4062 is formed in the end piece of the connection knob 406, in which the wedge 405 can be fastened with a screw.

A circular groove 402 is formed at each of the two ends of the rod body 401, with one end of the wedge 405 extending in the direction of the centering hole of the connection rotary knob 406 until it engages in the circular groove 402. To mount the short-handle rod 4, the rod body 401 can first be inserted into the first outer sleeve 104 so that the stop head 403 docks onto the stop hole 1041 in advance. When the connection rotary knob 406 is subsequently turned, the external thread on the end piece of the connection rotary knob 406 is then screwed onto the connection thread hole 3 of the first outer sleeve 104. In the meantime, both the rod body 401 and the first outer sleeve 104 each only have a certain amount of play for axial relative movement, i.e. without twisting the rod body 401. This will ensure that the counterweights 1 on both sides remain symmetrical and then dock easily.

A first grip sleeve 404 is attached to the outside of the rod body 401 to provide abrasion protection to the rod body 401 when it comes into contact with human hands. The first rod handle may be made of rubber or other material as needed to increase the frictional force relative to the hands.

In the current version, the fitness device functions as a dumbbell, whereby you can grab the middle point of the short handle bar 4 and then train your arm strength.

Embodiment III

With reference to 3 and 7 until 13 The present embodiment differs from the second in that two short handle bars 4 are provided, between which a long handle bar 5 is installed.

Specifically, the two ends of the long handle rod 5 are removably connected to the short handle rod 4.

The long handle bar 5 is provided with an inner sleeve 501, at each of whose two ends a second outer sleeve 503 is attached, which is screwed to the short handle bar 4, wherein the second handle sleeve 502 is attached to the outside of the inner sleeve 501. In the middle of the second outer sleeve 503, an internally threaded hole is formed, to which the connection rotary knob 406 on the short handle bar 4 can be screwed.

In the current version, the fitness equipment functions as a barbell, whereby you can grab the middle point of the long handle bar 5 and then carry out a workout.

Embodiment IV

Regarding 4 The present embodiment is differentiated from the first in such a way that the handle 2 is attached to an end of the counterweight 1 facing away from the threaded connection hole 3, so that the fitness device is suitable for training as a kettlebell with a different structure from the first embodiment.

Embodiment V

Regarding 5 The present embodiment differs from the second in that the handle 2 is attached to an end of the counterweight 1 facing away from the threaded connection hole 3, so that the fitness device is suitable for training as a dumbbell with a different structure from the second embodiment. Since the handle 2 is attached to the end piece and the center of gravity therefore falls in the middle of the bar handle, accidents due to the shift in the center of gravity are avoidable.

Embodiment VI

Regarding 6 In the present embodiment, a long bar based on the fifth embodiment is introduced so that the fitness device can be used as a barbell for training. Since the handle 2 is also attached to the end piece and the center of gravity therefore falls on the middle of the bar handle, accidents due to the shift in the center of gravity are avoidable.
